R421A is a hydrofluorocarbon (HFC) refrigerant blend that is designed as a replacement for R22 in various air conditioning and refrigeration applications. It is formulated to have a lower environmental impact, with a lower ozone depletion potential and a lower global warming potential (GWP) compared to R22. R421A is often used as a retrofit refrigerant for existing R22 systems, providing a more environmentally friendly alternative while maintaining good performance and energy efficiency.
